Issues with Ports on Windows Servers

I have come across a number of comments in forums about asking how to determine what software is using a particular port.  This query happens when you are trying to install software which fails due to a port being utilized already.  I came across the same query and remembered that I could do this using NETSTAT but couldn’t remember the switches.  Well I found the information and thought I would share:-

netstat -aon | findstr

Eg: with port 443



If you kill the related process then the port will be become free.

Note : Normally PID column will not be visible in task manager , but the same you can find in View -> Select columns
